Yes, thanks, I know about measuring PD on one's self but given that it was already measured "professionally" I hoped to have that result (which, if I understand the law, is my property because it's part of my health care record).
And there's no reason I couldn't use FLEX with Zenni but I had about 2 hours before every optician in my area closed, on a Sunday if I recall, to spend the money having put things off all year long. I didn't have a current prescription so I needed an optometrist to determine it for me before I could order anything. And for what my FLEX paid at LensCrafters I could have bought roughly 40 pairs of glasses at Zenni. In fact, about a year or so later, I ordered two pairs from Zenni for around $12 each and they were every bit as good as what I got from LensCrafters. But I needed the prescription and I needed it that day or the FLEX would have evaporated.
